2017-04-12ALSA: usb-audio: Add native DSD support for TEAC 501/503 DACNobutaka Okabe
[ Upstream commit 7f38ca047b0cb54df7f6d9e4110e292e45dba6ad ] This patch adds native DSD support for the following devices. - TEAC NT-503 - TEAC UD-503 - TEAC UD-501 (1) Add quirks for native DSD support for TEAC devices. (2) A specific vendor command is needed to switch between PCM/DOP and DSD mode, same as Denon/Marantz devices.

2017-02-14Revert "ALSA: line6: Only determine control port properties if needed"Takashi Iwai
commit f3d83317a69e7d658e7c83e24f8b31ac533c39e3 upstream. This reverts commit f6a0dd107ad0c8b59d1c9735eea4b8cb9f460949. The commit caused a regression on LINE6 Transport that has no control caps. Although reverting the commit may result back in a spurious error message for some device again, it's the simplest regression fix, hence it's taken as is at first. The further code fix will follow later.

2017-01-15ALSA: usb-audio: Add a quirk for Plantronics BT600Dennis Kadioglu
commit 2e40795c3bf344cfb5220d94566205796e3ef19a upstream. Plantronics BT600 does not support reading the sample rate which leads to many lines of "cannot get freq at ep 0x1" and "cannot get freq at ep 0x82". This patch adds the USB ID of the BT600 to quirks.c and avoids those error messages.

commit 4763601a56f155ddf94ef35fc2c41504a2de15f5 upstream. The function returns -EINVAL even if it builds the stream properly. The bogus error code sneaked in during the code refactoring, but it wasn't noticed until now since the returned error code itself is ignored in anyway. Kill it here, but there is no behavior change by this patch, obviously.

2017-01-12ALSA: usb-audio: Fix irq/process data synchronizationIoan-Adrian Ratiu
commit 1d0f953086f090a022f2c0e1448300c15372db46 upstream. Commit 16200948d83 ("ALSA: usb-audio: Fix race at stopping the stream") was incomplete causing another more severe kernel panic, so it got reverted. This fixes both the original problem and its fallout kernel race/crash. The original fix is to move the endpoint member NULL clearing logic inside wait_clear_urbs() so the irq triggering the urb completion doesn't call retire_capture/playback_urb() after the NULL clearing and generate a panic. However this creates a new race between snd_usb_endpoint_start()'s call to wait_clear_urbs() and the irq urb completion handler which again calls retire_capture/playback_urb() leading to a new NULL dereference. We keep the EP deactivation code in snd_usb_endpoint_start() because removing it will break the EP reference counting (see [1] [2] for info), however we don't need the "can_sleep" mechanism anymore because a new function was introduced (snd_usb_endpoint_sync_pending_stop()) which synchronizes pending stops and gets called inside the pcm prepare callback. It also makes sense to remove can_sleep because it was also removed from deactivate_urbs() signature in [3] so we benefit from more simplification.

commit 995c6a7fd9b9212abdf01160f6ce3193176be503 upstream. Sampling rate changes after first set one are not reflected to the hardware, while driver and ALSA think the rate has been changed. Fix the problem by properly stopping the interface at the beginning of prepare call, allowing new rate to be set to the hardware. This keeps the hardware in sync with the driver.

The usb-audio driver implements the deferred device disconnection for the device in use. In this mode, the disconnection callback returns immediately while the actual ALSA card object removal happens later when all files get closed.

2016-09-25ALSA: usb-line6: use the same declaration as definition in header for MIDI ↵Takashi Sakamoto
manufacturer ID Currently, usb-line6 module exports an array of MIDI manufacturer ID and usb-pod module uses it. However, the declaration is not the definition in common header. The difference is explicit length of array. Although compiler calculates it and everything goes well, it's better to use the same representation between definition and declaration. This commit fills the length of array for usb-line6 module. As a small good sub-effect, this commit suppress below warnings from static analysis by sparse v0.5.0. sound/usb/line6/driver.c:274:43: error: cannot size expression sound/usb/line6/driver.c:275:16: error: cannot size expression sound/usb/line6/driver.c:276:16: error: cannot size expression sound/usb/line6/driver.c:277:16: error: cannot size expression Fixes: 705ececd1c60 ("Staging: add line6 usb driver") Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2016-09-23ALSA: usb-audio: Extend DragonFly dB scale quirk to cover other variantsAnssi Hannula
The DragonFly quirk added in 42e3121d90f4 ("ALSA: usb-audio: Add a more accurate volume quirk for AudioQuest DragonFly") applies a custom dB map on the volume control when its range is reported as 0..50 (0 .. 0.2dB). However, there exists at least one other variant (hw v1.0c, as opposed to the tested v1.2) which reports a different non-sensical volume range (0..53) and the custom map is therefore not applied for that device. This results in all of the volume change appearing close to 100% on mixer UIs that utilize the dB TLV information. Add a fallback case where no dB TLV is reported at all if the control range is not 0..50 but still 0..N where N <= 1000 (3.9 dB). Also restrict the quirk to only apply to the volume control as there is also a mute control which would match the check otherwise.

2016-08-22ALSA: line6: Give up on the lock while URBs are released.Andrej Krutak
Done, because line6_stream_stop() locks and calls line6_unlink_audio_urbs(), which in turn invokes audio_out_callback(), which tries to lock 2nd time.
